Please refer to Fig. 1-5, a kind of novel shock proof pressure transmitter sensing device of bradyseism, including first shell 1, first The bottom of shell 1 is provided with second shell 2, and first shell 1 is fixedly connected by the connector sleeve 3 with second shell 2, and second There is rotating bolt 4 in the bottom of shell 2 in horizontally disposed, and the inside of rotating bolt 4 is fixedly connected with screwed pipe 5, rotating bolt 4 Top is fixedly connected with iron plate in level, is fixedly connected by four helix tubes 7 with iron plate at the bottom corners of second shell 2, The bottom centre of second shell 2 passes through the company of 2 bottom centre of second shell in connecting rod 6, the top of connecting rod 6 is vertically arranged with The inside of interface 8 and second shell 2 is interconnected, and the bottom of second shell 2 is in be fixedly connected with pressure sensor piece 9, feeling of stress Answer the top of piece 9 to be provided with data line 10, the inside of data line 10 and first shell 1 is connected with each other, the bottom of connecting rod 6 with turn The top iron plate of dynamic bolt 4 is interconnected.
Rotating bolt 4 is fixedly connected with screwed pipe 5, and screwed pipe 5 is internally provided with accommodating chamber 11, the top of screwed pipe 5 It is provided with outlet, and connecting rod 6 is interconnected by outlet and accommodating chamber 11, so that internal liquid fluid not will receive resistance Gear, more smoothly.
The inside of helix tube 7 be it is hollow, the outer wall of helix tube 7 is surrounded with rubber layer 12, and the outer wall of rubber layer 12 is in It is surrounded with insulating layer 13, can be improved the elasticity and thermal insulation property of helix tube 7, prevents liquid from excessive expand with heat and contract with cold occur Phenomenon effectively improves precision.
The bottom of screwed pipe 5 is provided with flexible sheet 14, and the bottom interior wall of screwed pipe 5 is in be surrounded with card slot, elasticity The side wall of diaphragm 14 passes through the mutual clamping of side wall of card slot and screwed pipe 5, and card slot is internally provided with sealing ring, prevents internal liquid There is the phenomenon that seepage flow in body.
The inside of accommodating chamber 11 is filled with silicone oil, is also filled with silicone oil inside the pipeline of helix tube 7, and silicone oil is by helix tube 7 and the inner space of accommodating chamber 11 be filled up completely, internal silicone oil can separate monitored liquid and pressure sensor piece 9, It prevents measured matter from polluting pressure sensor piece 9, improves service life, can also prevent fluid to be measured from entering in electrical component Portion damages electrical component.
First shell 1 is internally provided with circuit board, and the side of circuit board is provided with display, and display is located at first shell The side wall center of body 1, the bottom of circuit board are connected with data line 10.
The shell of first shell 1 and second shell 2 is that steel is made, and first shell 1 and the surface of second shell 2 are equal It is provided with anti-corrosion paint, second shell 2 is rectangle, and the sidewall paneling of the close display side of second shell 2 passes through bolt It is fixedly connected with the inside of second shell 2, internal helix tube 7 and flexible sheet 14 are combined with each other, and can receive diaphragm Surge be transmitted in pressure sensor piece 9, since helix tube 7 is rubber helical shape, have certain elasticity, so Release can be carried out to instant impact by spiral helicine pipeline when by hydraulic shock, prevent excessive moment impact The case where power destroys pressure sensor piece 9.
Working principle: in use, instrument is located at pipeline external, screwed pipe 5 is mounted on the top of pipeline, with monitored pipe Road or container are connected with each other, and the flexible sheet 14 of 5 bottom of screwed pipe are contacted with tested hydraulic oil, and first by nature Pressure set, at work, fluid to be measured causes pressure to change by the switch of gate, when pressure rise it is big when outside Measured matter the flexible sheet 14 of 5 bottom of screwed pipe is squeezed, since flexible sheet 14 is flexible, so working as Flexible sheet 14 to the inside of screwed pipe 5 carries out deformation after being squeezed, but the inside center of screwed pipe 5 is provided with accommodating chamber 11, and since the inside of accommodating chamber 11 has been completely filled silicone oil, so the silicone oil inside accommodating chamber 11 passes through accommodating chamber 11 The outlet at top is moved to the inside of helix tube 7, and the liquid inside original helix tube 7 is squeezed to 8 side of connector Pressure, the bottom for finally reaching pressure sensor piece 9 squeeze pressure sensor piece 9, and pressure sensor piece 9 is extruded generation deformation, And the resistance of pressure sensor piece 9 is caused to generate variation since pressure sensor piece 9 generates deformation, the variation of resistance causes electric current Variation, the current signal of variation is transmitted to by circuit in first shell 1 by the inside of first shell 1 by data line 10 Current signal is transformed into digital signal and is finally transformed into figure signal by the converter of plate to be exported over the display, user The variation of pressure can be observed in the display in first shell 1, and the external liquid for having impurity can be isolated in this way, prevent Only they pollute to pressure sensor piece 9 and then influence the service life of electrical component, when pressure decreases due to accommodating chamber 11 Internal liquid itself be to fill up, so internal liquid flows back again after pressure reduction, by flexible sheet 14 again Ejection, when there is biggish instant impact since helix tube 7 is arranged in the shape of a spiral, so pressure can not arrive moment Up to pressure sensor piece 9, vibration can be disintegrated inside spiral helicine helix tube 7, can slow down the moment to electrical component Impact, preferably protects device, and when high pressure is normal pressure, since pressure is lasting, so in helix tube 7 Portion can persistently be squeezed the pressure of the silicone oil to come by accommodating chamber 11, so that persistently applying to pressure sensor piece 9 inside helix tube 7 Pressure, so pressure sensor piece 9 can sense normal high pressure, so that pressure signal transmission be gone out.
